I am not a big manual guy except for landscape work, but I really want a faster portrait/normal than the f/1.8 on native lenses. I am thinking 50-58mm and <= f/1.4 would suffice. I have admired the dreamy bokeh and the film-like rendering of the Rokkors many of you use. If I am trying to stay under $100, what are some suggestions? Thanks in advance for your help.
